    Are you referring to the bobbin case or the bobbin winder? Also, when you turn the hand wheel toward you, can you see the hook turning in the bobbin case area?

SOURCE: Upper thread knots up with bobbin thread when sewing a stich

Thread test
Test your thread quality to start, thread your machine and LIFT the presser foot (this opens the tension disks). Pull your top thread straight back. If you feel no tension no mater how much thread you pull, your thread is good. If that your machine passes that test, then let me know, we can go to step 2. If not, try different spool of thread, same test until you get a smooth pull (tip: always check your thread this way when you thread your machine)
Step 2:
Pull on your threaded bobbin thread while it’s in the machine. Does it pull smooth and even? If so, go to step 3. If not, try a new bobbin (bobbins get bent or distorted if wound too tight).
Clean thoroughly in the hook and bobbin case area and oil 1-2 drop is all.
Thread knotting on the bobbin can be a lot of things but here's some guidance:
Tension:
If the thread is loose on the bottom of the fabric, it's actually the top thread is too loose. Think of 2 little elves playing tug of war in your machine, one on toip and one underneath. If you have loops on bottom, the top needs to pull harder (tighten top tension)
Jamming bobbin case:
If it is damaged from turning out of place once, it could have rough spots on it that makes the thread hang on it, and keeps making it turn over and over. Use a finger nail board (fine sanding) and smoothall rough spots. Then reset the bobbin case taking care to put the notch in the bobbin case in alignment with the proper spot in the machine (basically 5 o’clock) when looking at the round area where the bobbin case goes.

Hi - it is possible that your needle is bent. Insert a new needle and check again - if you have the same problem, your timing is probably off. You could try buying a new bobbin case to see if that solves the problem. If you have had your machine tuned up within the last year or two, I would recommend a tune-up. If you know of a reputable sewing machine repair shop or dealer, the tune up should include correcting the timing and will extend the life of your machine.


Good luck,

Ginny

SOURCE: Bobbin winder won't spin

The two most common problems are that you either need a new bobbin tire, or just need to adjust the position of the winder a little closer to the hand wheel. Remove the top cover and you will see the winder assembly. Loosen the two screws that hold the assembly nudge it closer to the hand wheel side. If you move it too far the winder will constantly spin. Also, examine the rubber tire, it may have a flat spot on it in which case it needs to be replaced. If it is worn out you may not be able to tell just by looking at it.
These winders can be tricky to adjust but why not try?
Good luck!

SOURCE: timing my pfaff 332 sewing machine

There are two parts to the sew hook on that machine. The outer part has the hook point that grabs the thread off the needle. Then there is an inner part which has a post in the center of it that the bobbin case fits on to. The inner part should be held in place with an arm that has a bump on it. It keeps the inner part from spinning around. Sometimes this arm slips loose and a notch in the inner part of the hook assembly slips out from under the knob on the arm. If this is what is happening, you need to loosen the screw holding the arm in place and reposition the notch of the inner part of the hook back under the bump on the arm. There needs to be clearance between the notch and the bump for the thread to pass between the two. And the bump should be in line with the needle when it is in its lowest position.
If this doesn't solve the problem you need to take the machine in for repair.

SOURCE: bobbin holder won't stay put

If the bobbin case/holder is trying to lift up and the thread is staying partly around it, your bobbin case may have turned part way.
Remove the needle plate and the bobbin case. The outer edges of the bobbin case should be very smooth. I suspect you may see a needle hole in the flat area that was under the foot. If so, you will probably wish to take it to your dealer and show them. They may smooth it or recommend replacing it. When the bobbin case is placed back into the hook cup that it sets in, the retainer at the 11 o'clock position on it should only allow the case to lift up about 0.8 to 1mm at the most. If it will lift up more than this, press down firmly on the retainer and move it closer to the bobbin case. You must have enough room for the thread to pass between the retainer and the bobbin case, but too much clearance will allow the bobbin case to turn in the machine and it will be damaged by the needle.

SOURCE: Tension Problem on Pfaff 2034, bobbin loops

Rule of thumb.. Loops on the bottom, problem on the top. Loops on the top, problems on the bottom.

Set your upper tension at 4, and rethread the machine from the top. Just before you thread the needle, but the presser foot down. If the thread pulls right thru easily, then the thread is not thru the tension wheel right. Because, if you can't pull the thread thru with the presser foot down, you have it threaded right.

My pfaff 4.2 keeps saying remove thread jam under the stitch plate. I have cleared everything several times but it keeps coming up on the screen.


Candace, while not familiar with the 4.2, I've had thread jams on my trusty old Pfaff. I hope this helps!

If you are able to totally remove the bobbin cover/stitch plate, please do so. Ideally, there will be one or two screws holding it in place.

remove the bobbin

carefully inspect the bobbin housing; thread likes to hide behind the housing. If you find some thread, use a tweezers to remove it.

If no thread is found, see if there are one or two screws holding the bobbin holder/raceway in place, or just a lever. Try to remove the bobbin holder, carefully noting what the orientation is of all pieces is (using a cellphone to capture pictures of before and after is great!).

Clear any threads from the raceway, carefully re-assemble everything, test and good luck!!!

I have not even used my Pfaff expression 2036, and it is locked up?


your oil has dried up and seized the machine. Take it in for cleaning and lubing... might has well have them adjust the timing too.

It is likely the the bobbin holder is jammed up with cloth or thread. Take the bobbin holder out and turn the machine by hand, if it does not move it could have a broken timing belt or slipping coupling.

Needle hits the bobbin holder and doesn't grab the bobbin thread


Check you have the right size bobbin case the gap where the needle enters should be 13mm approx at the widest point. A lot of other pfaff bobbin cases seem to fit and can be easily be mistaken. I have two pfaffs and have accidentally mixed the cases and had a similar problem.

Pfaff 1222 Bobbin holder stuck with thread


With power off, take the needle out and the presser foot. Remove the two flathead screws that secure the needle plate from the machine and remove the plate. You'll have a top view of the bobbin housing and see the thread that's stuck to it.
